WebJul 19, 2002 · Short sampling times were beneficial to all compounds. Combined with static sampling, the low-affinity compounds were favored, i.e., the calibration curves were linear on a wider range. Dichloroethane presented a linear calibration curve between 5 and 980 μg m −3, acetone between 4.7 and 300 μg m −3 for 1 min in static WebAir monitoring to determine a worker’s exposure involves measuring the level of an airborne contaminant in the breathing zone of workers using a personal sampler during their usual work activities, including routine breaks. Figure 2 shows an approximation of a worker’s breathing zone. Figure 2 Worker’s breathing zone
